While the rest of the country has been frozen, California is having a winter heatwave. Yesterday San Francisco set a new record high for the date at 74F (23C,) and there may be another record high today. Since I’m fortunate to live someplace with a mild climate, and I’m able to grow orchids outdoors all […]
As we move through the last few days of autumn, in the Northern Hemisphere at least, don’t panic if your orchid drops some leaves or looks a little peaked. With less light and cooler days, many orchids are resting in their dormant periods. If your plant is otherwise healthy, and a few leaves drop, it’s […]
I’ve heard orchid growers say that if nothing’s dying, then you’re not learning anything. True to form, when I kill an orchid, I try to figure out what went wrong so that I don’t repeat the mistake. With my coroner’s hat on, I’ll show you these pictures from happier times, before this orchid kicked the […]
More people kill their orchids through overwatering than any other cause. Fall is particularly perilous time for overwatering, as plants start to go dormant, but people unwittingly continue the same watering regimen as they did in the growing season. With too much water, orchid roots will rot, and the leaves will follow. So this is […]
It feels like an embarrassment of riches to say that some of my orchid flowers last so long that they get dusty. Under ideal conditions, Phalaenopsis, Paphiopedilum, Epidendrum, and Cymbidium flowers can last for months, and dust can be a problem. Most orchid flowers can handle a gentle touch with clean hands or a clean […]
Like all plants, orchids need a healthy root system to survive and thrive. At least once a year, orchids enter a growth cycle when they generate new roots. These new roots are light green at the tips, and turn white with time. As they age over several months, they may turn brown. Since orchids are […]
As the long days of late summer unwind, most orchids should be enjoying a period of growth. Besides light and fertilizer, water is an essential element for healthy new growth. These watering tips can help you avoid some of the most common orchid care problems. – When you water, use more than just a few […]
If an orchid refuses to bloom over the course of a year, one of the most common culprits is insufficient light. Here are a few tips to keep in mind: • Light green or medium green leaves are a good indication that an orchid is receiving sufficient light. Dark green leaves may look attractive, but […]
Well, not dragons really, but dragonflies. This one landed on a branch and stayed long enough to pose for Dave’s camera. With a little research, we identified it as a Blue-eyed Darner Dragonfly (scientific name Aeshna multicolor,) native to North America west of the Mississippi River. So what does this beautiful blue creature have to […]
Well, a little sub-tropical heat wave, anyway. We’ve had almost 3 weeks of fog-less days, unusual weather for this time of year in San Francisco. For the past few days, it’s stayed in the 80’s or 90’s F (27-37C.) That’s warm for us, since the fog bank usually starts to air-condition the coast in spring. […]
